Abstract

Although the genomic sequences of a number of Archaea have been completed in the last three years, genetic systems in the sequenced organisms are absent. In contrast, genetic studies of the mesophiles in the archaeal genus Methanococcus have become commonplace following the recent developments of antibiotic resistance markers, DNA transformation methods, reporter genes, shuttle vectors and expression vectors. These developments have led to investigations of the transcription of the genes for hydrogen metabolism, nitrogen fixation and flagellin assembly. These genetic systems can potentially be used to analyse the genomic sequence of the hyperthermophile Methanococcus jannaschii, addressing questions of its physiology and the function of its many uncharacterized open reading frames. Thus, the sequence of M. jannaschii can serve as a starting point for gene isolation, while in vivo genetics in the mesophilic methanococci can provide the experimental systems to test the predictions from genomics.
